Description A study was c arried ou t wi t h ten mungb ean genoty pe s and three mi crobial tre atments to est imate
the genot y p i c variat ion f or root in f ection to Piriformospo r a i ndica , nodulati on, N and P uptake and yield
comp onents and also to iden tify the genoty pes resp onsive to mungb ean Rhiz obi um and P. ind i ca.

genoty p es, however, i ts effec t wa s ob served only in a few genoty p es f or plan t height, P content in shoot ,
100 seed weight and gr ains and se ed yie ld. The e ff e ct of comb ined i noculation (R+P) coul d be observed in
N content in grain, P. ind i ca i n f ection in roots and seed yield. MH-8 10 and MH-721 were the onl y
genoty p e i n which t he effect o f al l t he three inoculants was observed. MH-421exhi b i ted max imum response
